W. H. KNQBLOCH CORNER STRUCTURE Filed July 3, 1928 Patented Nov. 12, 1929 UNITED STATES PATENT OFFICE WALTER H. KNOBLOCH, OF ERIE, PENNSYLVANIA, ASSIGNOR T0 ERIE ART METAL COMPANY, OF MILLCREEK TOWNSHIP, ERIE COUNTY, PENNSYLVANIA, A CORPORA- TION OF PENNSYLVANIA Application filed July 3, 1928.

In forming cases having metal faces, such as refrigerator cases, difliculty has been experienced in finishing the corners. This is particularly true where the metal faces of the Walls have enamel finish. It is desirable to bevel the edges of the corner strips and where this is done and they are brought up tight against the enamel finish the sharp edges of the strips crack the enamel and further the sheared edges do not make as fine a finish as is desirable. The present invention obviates this difiiculty. Features and details of the invent-ion will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows Fig. 1 shows a perspective View of a portion of a case such as is ordinarily used for refrigerators.

Fig. 2 a front View of a corner of thecase, slightly enlarged.

Fig. 3 an enlarged section on the line 3-3 in Fig. l.

1 marks the walls of the case. These are provided with the wall plates '2, which plates are preferably coated with enamel 3. The

wall plates are secured on a frame 4-. and when used for refrigeration insulating material 5 is provided within the wall plates and a lining 5 within the insulating material.

Corner strips 6 are arranged along each of the corners, these corner strips being of angle form in cross section and overlapping adjoin- 7 ing plates 2. These angle strips have the beveled edges 7 which seat at 8 upon the side.

plates 2. A fold 9 is formed in the extreme edges of the plates, these folds being folded down closely on the beveled portion 7. The folded edge 10 forms a seating surface at 8 and the exposed edge of the strip is nicely rounded by the fold.

The corner strips are provided with countersunk openings 11, the beveled edges lifting the strips sufiiciently from the plates 2 to afford clearance for the countersunk portion and sorews12 pass'through these openings into the wall securing the corner strips in place.

Corner pieces 13 are arranged over the CORNER STRUCTURE Serial No. 290,235.

plates extending from the corner; and a cor-.

ner strip of angle form in cross section overlapping the wall plates, the strip being folded back upon itself at its edges and the fold edges beveled and seated upon the faces of the wall plates. 1

2. A corner structure comprising wall plates extending from the corner; and a corner strip of angle form in cross section overlapping the wall plates, the strip being folded back upon itself at its edges and the fold edges beveled and seated upon the faces of the wall plates, said corner strips having countersunk openings and screws in the openings.

3. A corner structurecomprising wall plates extending from the corner, said plates having enamel faces; and a corner strip of angle form in cross section ovelapping the wall jplates, the strip being folded back upon itself at its edges and the fold edges beveled and seated upon the faces of the wall plates.

In testimony whereof I have hereunto set my hand.
